In the closing scene of James Michener's novel The Bridges of Toko-Ri, an admiral thinks of the aircrew he just sent to the Korean conflict--some never to return--and asks, "Where did we get such men?" President Ronald Reagan asked the same question years later at the Medal of Honor presentation to Master Sergeant Roy P. Benavidez, speaking of both the awardee and his many comrades in Vietnam. It is often overlooked that many who served in both of those conflicts came from the activated reserve forces and selective service. During their year at the Army War College, Kent Park and Stephen Trynosky examined the challenges if we had to again rapidly expand the army for a large war. They join podcast editor Ron Granieri to discuss their research on the topic and their concerns that the U.S. is not adequately prepared for a major conflict with a near-peer threat, such as China or Russia. Park and Trynosky argue that the U.S. needs to take steps to increase its personnel readiness long before the shadow of great power conflict appears because timelines in the modern global security environment are much more compressed than in previous conflicts.
